Quantitative Rietveld texture analysis of CaSiO3 perovskite deformed in a diamond anvil cell

L. Miyagi, S. Merkel, T. Yagi, N. Sata, Y. Ohishi and H.-R. Wenk

The Rietveld method is used to extract quantitative texture information from a single synchrotron diffraction image of a CaSiO3 perovskite sample deformed in axial compression in a diamond anvil cell. The image used for analysis was taken in radial geometry at 49 GPa and room temperature. We obtain a preferred orientation of {100} lattice planes oriented perpendicular to the compression direction and this is compatible with {110}110 slip.
